WATER-FILTER.

SPECIFICATION forming part of Letters Patent No. 243,975, dated July 5, 1881.

Application filed April 9, [881.

To all whom it may concern Be it known thatI, UHARLEs L. RIDGWAY, of Boston, in the county of Suffolk, and in the State of Massachusetts, have invented certain new and useful Improvements in Water-Filters and I dohereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying draw.- ings', making a part of this specification, in which- Figure lis a perspective view ofmy improved filter, a portion of one head being broken away to show the interior construction at such point.

Fig. 2 is a horizontal section of the same upon a central longitudinal line, and shows the arrangement of parts to pass water directly through the pipes without'filtration. Figs.3 and at are vertical sections upon line at :r of Fig. 2, and show the arrangement of parts necessary to direct water in opposite directions through the filtering material; and Figs. 5 and 6 are respectively a central longitudinal section and a central cross-section, showing the water-ways arranged at the axial center of the casing.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to furnish an inexpensive and efficient means whereby water may be cleansed from impurities held therein in suspension; and to this endit consists, principally, in the construction of the cock which controls the passage of water through the filter and its combination with the casing, substantially as and for the purpose hereinafter shown.

It consists, further, in the construction and combination of the parts of the filter, substantially as and for the purpose hereinafter set forth.

In the application of my improvements I use a cylindrical casing or shell, A, which has any desired dimensions, and isinclosed at each end by means of :a head, B, that has preferably a central portion, 1), that is concave interiorly.

Within one side of the casin g A are provided two waterpassages, O and O, which at their outer ends open into and connect with the con cave interiors b of the heads B, and at their inner ends intersect a water passage or way, D, that has a line at right angles thereto, and

ModeL) is adapted at one or both of its ends for connection with a faucet or with water-pipes.

Fitted into a round tapering opening that is provided at'the intersection of the passages O and O and D is a correspondiugly-shaped plug, E, which is adapted to be rotated in the same manner as the plug of an ordinary cock, and upon opposite sides is provided with transverse semicircular grooves e and e, that coincide with ports 0 aiid c, that furnish communication between said passages. Thedepths of the grooves c and c are such as to leave between their bottoms a solid portion, 0 of the plug E, which has less thickness than the diameter of the passage D, so that when said plug is adjusted to bring said part in a line with said passage, as shown in Fig. 2, it does not fill the same, and water will pass through the said grooves c and 0, so as to render said passage D continuous and direct. When the plug E is turned in either direction one-fourth of a revolution it assumes the position shown in Figs. 3 and 4, and causes the portions of the passage D above and below said plug to be each connected through the grooves or ports 6 and c with one of the passages O and O.

The apparatus is intended principally for use upon a faucet, in which event water would enter at the upper end and be discharged from the lower end of the passage D, and with the plug E arranged as shown in Fig. 3 the course of water would be from the upper portion of said passage, through the ports 0 and c and passage 0, into the body of the casing A, and through the same, the passage 0, and ports 0 and 6 into the lower portion of said passage D, as indicated by arrows, while by turning said plug to the position shown in Fig. 4: the course of the water through said casin g would be reversed, as seen by the arrows of said figure.

The casing A is filled with charcoal or other suitable filtering material, and suchfilling is secured in place by means of two diaphragms, F, made of or from wirecloth or reticulated sheet metal, one of which diaphragms is placed at each end of said casing within a right-angled groove, a, provided at such point, and is held in position by means of two open metal disks, G, that are placed upon opposite sides of said part and just fill said groove. The head B bears against the outer face at the edge I w i I of the outer disk and holds said parts securely in place.

In use all removable matter held in suspension within the water will be deposited within the end of the casing and within the adjacent filling at which said water enters, and when such accumulation prevents the perfect operation of the filter it may be removed by reversingthe direction of the current and causing the deposit to be carried outward and downward.

For convenience of theinsertion and removal of the filling, an opening, a, closed by means of a screw-cap, a is provided within opposite sides of the casing A, such arrangement renderin g unnecessary the removal of the heads B or the disconnection of the filter from the pipes.

The construction shown enables the body or casin g of the filter to be placed wholly in rear of a faucet, where it occupies no available space and does not interfere with the free use of said faucet; but, if desired, said casing may have the construction shown in Figs. 5 and 6, the water-passages O and 0 arranged at the axis of said casing, and the passage D caused to pass centrally through the latter.

If desired, the casing A may be made square instead of round, so as to permit its capacity to be increased by horizontal enlargement without increase of its vertical dimensions.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s 1. In combination with the passage D, and with the ports 0 and c, the plug E, located at the intersection of said passage and ports, provided with the ports 6 and e, and adapted by rotation to direct water through either of said ports 0 and 0 into and through the filtering material, or to cause said water to pass directly through said passage D without filtration, substantially as and for the purpose specified.

2. The hereinbefore-described filter, in which the casing A, provided with the heads B and B, passages G, O, and D, and ports 0 and c, is combined with the plug E, having the ports 0 and e, substantially as and forthe purpose set forth. I

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of April, 1881.

CHARLES L. RIDGWAY.
